150w mh ballast kit help

hello all long time reader first time poster, anyway i just ordered a 150w mh ballast kit and am needing to know where the cheapest place is to get the socket and cord. i saw htgsupply had one for $20 but it was like
$35 w/ shipping and that was too much (about the cost of the ballast). so if anybody knows, the help would be much appreciated!

i ordered a htg 150 ballast&host combination that was already all wired up for 75 bucks

i already ordered my 150w mh ballast kit, ive read the htgsupply ballast are poorly made and have read the ballast i ordered could last 50 years. i just need the socket and cord for it and have come across threads saying i could get like a $6 socket and use an orange extention cord, but now i cant find it.

hmm ballast i ordered turned out to be out of stock, just out of curiosity what did your 150w system come with?
